It's why your body continues to produce thick, stuck mucus long after a virus.

The Shocking Science Behind Mullein

Mullein plant with yellow flowers — beloved in herbal tradition

Mullein has been beloved in herbal tradition for centuries — across Europe, North America, and parts of Asia.

People reached for it for issues like:

  • Stubborn mucus that won't move
  • Constant coughing
  • Thick phlegm
  • Feeling stuffed up all the time

We decided to scrutinise the research.

We looked over looking at mullein's properties to see how it actually works.

What we found ended up being shocking.

📚 The 10 Studies We Reviewed
Study 01 · 2021
Anti-Inflammatory Activity of Mullein Leaf Extract
Phytochemical Analysis and Anti-Inflammatory and Anti-Osteoarthritic Bioactive Potential of Verbascum thapsus L. Leaf Extract. PMC8434610. 2021.
Finding: Mullein leaf extract significantly decreased multiple inflammation markers (IL-6, COX-2, iNOS, MMPs) in laboratory cell models — the same inflammation markers Imperial College London identified as elevated in long-COVID patients.
Study 02 · 2024
Multifaceted Biological Properties of Verbascoside
MDPI Antibiotics, PMC12291726. 2024.
Finding: Mullein's signature compound verbascoside has documented anti-inflammatory, antioxidant, and immunomodulatory effects confirmed across multiple in vitro and in vivo studies.
Study 03 · 2024
Antiviral Activity Against Human Coronaviruses
Referenced in PMC12291726 (2024 verbascoside review).
Finding: Mullein leaf and flower extracts showed antiviral activity against HCoV-229E — a human coronavirus in the same family as SARS-CoV-2 — as well as Hepatitis B virus and Herpes Simplex 2 in laboratory studies.
Study 04 · 2005
Expectorant + Bronchodilatory Effects
Phytotherapy Research, 2005.
Finding: Mullein extract demonstrated expectorant (mucus-clearing) and bronchodilatory (airway-opening) effects in animal models — direct mechanistic support for thinning and clearing thick mucus.
Study 05 · 2002
Biological Activity of Common Mullein
Turker & Camper. Journal of Ethnopharmacology, 2002. PubMed PMID 12241986.
Finding: Identified mucilage (3%) as responsible for soothing mucous membranes, and saponins as responsible for expectorant action. Also confirmed antibacterial activity against Klebsiella pneumoniae, Staph aureus, and E. coli.
Study 06 · 2014
Saponin Mechanism in Expectorant Therapy
Clinical Application of Expectorant Therapy in Chronic Inflammatory Airway Diseases. International Journal of Molecular Medicine, PMC3961124. 2014.

How Mullein Leaf Works

Mullein contains compounds that actually physically break down mucus so your body can get rid of it naturally.

They're called saponins — molecular plant compounds.

Their effects on mucus are unlike anything we've ever seen.

Researchers describe them as 'natural soap.' Think washing-up liquid on a greasy pan — but for the mucus in your throat.

Step 01

Saponins Go To Work

Mullein contains natural compounds called saponins.

The same compounds herbalists have relied on for centuries.

Inflamed sinuses being calmed
Step 02

The Mucus Loses Its Grip

When saponins reach the thick mucus in your airways, they break the bonds that hold it together.

The buildup that's been stuck there for months can finally start to move.

Saponins breaking apart mucus at a molecular level
Step 03

Like Softening Dried Glue

Think of it like this — your mucus has become like dried glue.

Saponins soften that glue and break it apart so it's no longer stuck.

When saponins come into contact with mucus, they reduce it's viscosity.

Once the mucus is loosened, it becomes thinner. More watery.

And your body can actually move the thin mucus. It drains. It clears.

How Mullein Was Forgotten

Vintage early 1900s patent medicine bottles in a museum case
Early 1900s

A wave of cocaine in over-the-counter remedies had created a national addiction crisis. When the government cracked down, mullein and other herbal medicines got swept up in the same suspicion.

For nearly a century, it disappeared from American medicine.

Until now.

What People Are Reporting

People who use mullein in 2026 are reporting the same things:

  • Waking up and being able to breathe clearly
  • Sleeping through the night without choking on mucus or waking up in a panic
  • Speaking clearly — without stopping to clear your throat mid-sentence
  • Feeling at ease — knowing the bacteria don't have a place to breed and multiply

And then something unexpected starts happening…

Their confidence starts to return.

Because when you're not the person coughing constantly at the dinner table…

When you're not the one everyone can hear hacking through the bathroom door every morning…

When you're not the one people hesitate to sit next to…

You become someone different.

You become the person who stays at the table.

Who talks without apologising.

Not sitting quietly in the corner — actually talking. Laughing.

Being the person everyone remembers them as.

You become you again.

The person who just… lives.

Without the mucus dictating every moment of every day.

But Here's The Problem With Mullein

Cups of weak mullein tea with caution warning

Most people only know about mullein tea.

But mullein tea is weak.

A single cup gives you about 500mg of mullein.

Health sources say you'd need up to 10 cups every day to get enough of the active compounds.

Most people try one cup. Feel nothing. And give up.

That's exactly why the doctors of the early 1900s didn't waste their time with tea.

They used concentrated mullein extracts — far stronger, far more reliable.

But there was a catch.

Those extracts were made with alcohol. Often 40% or higher — about the strength of vodka.

Alcohol can actually add to the very irritation you're trying to calm in the first place.

On top of that, most adults today don't want to start their morning with a daily dose of alcohol.

That's where a company called CleraVox comes in.

They took the same powerful mullein extract the old doctors trusted — and rebuilt it for the modern era.

Same potency, same effect on thick mucus — without the harsh alcohol.

Why we're endorsing CleraVox.

CleraVox brought back something that should never have disappeared in the first place — the same concentrated mullein extract the old American doctors trusted during the 1918 Spanish Flu pandemic.

The formula that worked. Just without the harsh alcohol the 1918 versions were made with.

If you're ever going to start your mullein journey, we have no doubt it should be with CleraVox.

How To Take CleraVox

Sublingual application of mullein extract under the tongue
Step 01

Place Extract Under Tongue

Squeeze 2 full droppers under your tongue. Hold for 10–30 seconds.

This lets the active saponins absorb directly — bypassing the digestion that destroys most of mullein's active compounds in tea.

Animated saponin compounds traveling through bloodstream
Step 02

Saponins Travel Through Your System

Within minutes, mullein's natural saponins begin absorbing into your body.

From there, they make their way to mucus membranes — where the thick buildup is sitting.

Step 03

Mucus Breaks Apart

Once the saponins reach the buildup, they go to work.

The thick, sticky mucus slowly begins to break apart. Your body can finally clear what's been sitting there.

Real People. Real Results.

Since COVID, my lungs felt so full it was like drowning when I lay flat in bed. Swallowing was a problem all the time, which gave me a persistent cough. The mucus was so thick that bits of food would get stuck in my throat.

I saw the doctor. He didn't prescribe anything. So I sent for some CleraVox Mullein. To my surprise, it helped almost immediately.

After about a week I could breathe more easily and control the cough better. As time went on, I could feel my lungs emptying — allowing me to take deeper breaths. It really does what it says. Great stuff.

After I got COVID 9 months ago, I started having severe mucus problems. I would cough so hard I'd throw up.

The mullein extract has loosened the mucus and significantly improved my quality of life.

“But I'm 67… Is It Too Late For Me?

No — and here's why.

This isn't about being young or old. It's about helping your body do what it already knows how to do.

CleraVox Mullein Super Strength is for people just like you — people who are fed up with dealing with their stubborn mucus problems.

This formula is gentle, non-habit-forming, and safe to use alongside most medications.

And no — you're not “too old” to find real relief. If you've been dismissed, ignored, or left without answers — this extract is for you.

I have nearly finished my first bottle. Despite my reservations about trying it, as I thought it would be some kind of gimmick, it has actually been a great help.

I have suffered with excess mucus for many years, constantly having to clear my throat during the night and day.

The result is that my mucus production is perhaps only 25% of what it was previously. I am so satisfied with the results that I have just ordered three more bottles.
